?? Remove that last line? I thought this issue only affected the T25 SKU when coupled with a particular voltage regulator that wasn't reprogrammed to explicitly support T25. Hence, shouldn't this code only be enabled for specific boards? > diff --git a/board/nvidia/common/board.c b/board/nvidia/common/board.c ... > /* > + * Routine: power_det_init > + * Description: turn off power detects > + */ > +static void power_det_init(void) > +{ > +#if defined(CONFIG_TEGRA2) > + struct pmc_ctlr *const pmc = (struct pmc_ctlr *)TEGRA2_PMC_BASE; > + > + /* turn off power detects */ > + writel(0, &pmc->pmc_pwr_det_latch); > + writel(0, &pmc->pmc_pwr_det); > +#endif > +} I can't tell how that code relates to the commit description. -- nvpublic _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
